Along with farming, the hills and creek were prized areas for the sawyers and splitters,[8] and a number of mines were established in the region from the mid-to-late 1800s. In 1844 the first silver-lead, manganese and iron mines were established in the area, while the 1890s saw a minor gold rush—although "only small quantities were extracted".

17农业发展的同时，山岭与小溪是锯木和分木的宝贵地区，[8]十九世纪中后期，大量矿藏业在该地区兴建。1844年首家银，铅，锰，铁矿在该地区设立，而19世纪90年代出现了小范围淘金热，虽然&只有少量开采&。
